Modern Dinos

Dinosaurs have survived through everything the Earth has thrown at them. But they had became few when humanity came to the scene with swords and shields. And back then they weren't called Dinosaurs. They were called Dragons. Many reliable sources through out history, Alexander the great, Marco Pollo, and a bunch of other people who I forget their names have ALL mentioned dragons. Plus, how is it that from EVERYWHERE in the world the descriptions of dragons are pretty much the same? and if the myth of dragons did come from fossils than how did the assemble them correctly and know they had scales instead of fur or hair? So follow Rex, a male brown T-Rex with human intelligence, Hobbse, a male super intelligent Tiger, Tex, a female red raptor who you REALLY don't want to mess with unless you have a death wish. They journey all around the world. Annnd they are all 3 years old... This should be interesting.
